摘　　要：盾构法隧道多修建于地下水位以下地层,尤其是在富水地层,其地质条件复杂,水压力更高,因此更容易发生透水情况,轻则造成施工困难、工期滞后,重则发生安全事故及社会事件。本文针对盾构盾尾涌水、螺旋输送机喷涌和铰接处涌水,从结构类型、渗水原因等方面进行深入分析,并从多个角度提出了现场防控技术措施。Shield tunnels are mostly built in the stratum below the groundwater level,especially in water-rich stratum.Its geological conditions are complex and the water pressure is higher,so it is more prone to water seepage.In less severe cases,it will cause construction difficulties and delay of construction period,and in serious cases,it will cause safety accidents and social events.Aiming at the water gushing at the tail of shield,the water gushing of screw conveyor and the hinge,this paper makes an in-depth analysis from the aspects of structural type and water seepage reasons,and puts forward on-site prevention and control technical measures from multiple angles.
